EFI partitioning scheme was reading the last reported sector of the
block device to look for the alternate GPT header, before it had
confirmed that it should.  This causes problems for devices with the
following problems:  a) those who misreport their size (typically
off-by-one), and b) those who fail when asked to read a block
outside their range.

This patch moves the test for the Protective Master Boot Record (PMBR)
ahead of the tests for the Primary and Alternate GPT headers.  If the
PMBR is not valid, the disk is assumed to not be a GPT disk.  This can
be overridden with the 'gpt' kernel command line option.  If the
Primary GPT header is not valid, the Alternate GPT header is not
probed automatically unless the 'gpt' kernel command line option is
passed.  If the both the PMBR and Primary GPT header are valid, then
the Alternate GPT header at the end of the disk is probed.

Also re-enables CONFIG_EFI_PARTITION for all architectures.

If you call drivers/md/dm-io.c:resize_pool on an empty pool and
mempool_create is unable to make the pool, the condition is not handled
correctly, resulting in an oops in mempool_destroy.

Trivial fix.

Minor changes required to port kprobes for sparc64.

- arch_prepare_kprobe() returns an integer.

- added arch_remove_kprobe().

- changes to access copy of original instruction, since kprobe_opcode_t
  insn[MAX_INSN_SIZE] is moved from struct kprobe to a struct
  arch_specific_insn.

Since it released the lock, the process lists may not
be valid any more, and we must repeat the loop rather than
continue with the next parent.

Use -EAGAIN to show this condition (separate from the
normal -EFAULT that may happen if rusage information could
not be copied to user space).

The patch adds a check at the beginning of i2c_del_adapter in case
someone attempts to remove an adapter that was never added in the first
place. This sounds like a good safety, as doing so will lead to an oops
at the moment. Also, I have a need for it in the latest version of my
i2c-amd756-s4882 patch. I need to remove the original adapter and
install the virtual ones instead, but I have no way to know if the
original adapter was succesfully added beforehand or not.

In big endian machines, the read*/write* accessors do a byteswap for an
inherently little endian PCI bus.  However, rivafb puts the hardwire in big
endian register access, thus the byteswap is not needed. So for 16- and
32-bit access, instead of read*/write*, use __raw_read*/__raw_write* for all
archs.

The patch below fixes two flaws in minix_clear_inode.

The first is that it tests bh which is never initialized.  (&bh is a
parameter of minix_V1_raw_inode, but that routine can fail and return
before it has set bh)

The second is that generic_delete_inode() goes BUG() in case inode->i_state
!= I_CLEAR.  Clearly, it is expected that inode->i_sb->s_op->delete_inode
does a clear_inode() at some point.  But minix_delete_inode() calls
minix_free_inode() and that routine can print an error and return early,
before calling clear_inode().

ppdev's ioctls are not available for 32bit apps on 64bit systems.  There
are four ioctls which take no argument at all (so they are compatible
between 32bit and 64bit), these numbers do not clash with any other ioctl
code, and so I see no reason why not applying patch below.

It solves problem VMware users are faced on 64bit systems if they want to
